The point-slope form of a line:

$y-y_0=m(x-x_0)$

We have:

$m=\dfrac{2}{5}\\\\(-4,\ -7)\to x_0=-4,\ y_0=-7$

Substitute:

$y-(-7)=\dfrac{2}{5}(x-(-4))\\\\y+7=\dfrac{2}{5}(x+4)$

What is the center of the circle with the equation x2 + y2 – 10x – 11 = 0 ?

Kaylis [27]

Rearrange to standard form:-

x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36

Center of circle = (5, 0) and radius = sqrt36 = 6

Dovator [93]

Answer:

-12

Step-by-step explanation:

The coordinates of B' are just 3 times the coordinates of B, so the multiplier in the dilation is 3.

C' is the point with coordinates 3 times the coordinates of C, making C'(3, -12).

The y-coordinate is -12.
